Hi.
I do Update with SaveOrUpdateCopy(). Now, I have attached an event for this:
this.EventListeners.SaveOrUpdateCopyEventListeners = new IMergeEventListener[] { new AuditableSaveOrUpdateCopyEventListener() };
In the AuditableSaveOrUpdateCopyEventListener, I have inherited from DefaultSaveOrUpdateCopyEventListener and overriden OnMerge():
public class AuditableSaveOrUpdateCopyEventListener : DefaultSaveOrUpdateCopyEventListener {
public override void OnMerge(MergeEvent evt) {
this.AddAuditableData(evt);
base.OnMerge(evt);
}
public override void OnMerge(MergeEvent evt, System.Collections.IDictionary copyCache) {
this.AddAuditableData(evt);
base.OnMerge(evt, copyCache);
}
private void AddAuditableData(MergeEvent evt) {
var entity = evt.Original as AuditableEntityBase;
if (entity != null) {
...
}
}
}
But when I now change properties in entity, they will not be saved to the database.
Can someone give me a tip, how I can add my auditable-data for SaveOrUpdateCopy?
Thank you.
Best Regards, Thomas
